NLMK began implementing HPGR technology in each of the plants four process lines in 2016. The first four grinding rolls supplemented traditional cone crushers and ball mills, and enabled the plant to boost the productivity of the sections by 12.5 and to grow iron ore concentrate output by 1
Feb 01, 2016 Edge effect is a condition widely observed in High Pressure Grinding Roll HPGR operations that gives rise to reduced comminution at the edges of the roll surfaces. This effect is caused by a reduction in the local crushing pressure at the edges of the rolls resulting from the sliding friction between the static cheek plates and HPGR feed material. Practically, this has an impact on equipment ...
